Ukuqina, ubulukhuni namandla wempahla ye-PTFE, kuncane kakhulu.Amandla ayo aqinile angama-21-28 MPa, amandla okugoba yi-11-14 MPa futhi ubude bungama-250% -300%.Izokhubazeka ngaphansi kwengcindezi yesikhathi eside futhi ijwayele ukukhasa lapho igcwele kakhulu.Izici zokusebenza ezingenhla ze-PTFE, ziholela ezicini zenqubo eyingqayizivele lapho usebenzisaUmshini wokushushuluza wefilimu we-PTFEukusika.
1. Amandla amancane okusika.Ngenxa yokuqina, amandla, nobulukhuni be-PTFE buphansi, ngaphansi kwezimo ezifanayo zokusika, amandla amakhulu okusika ukusika insimbi engu-45 izikhathi ezingu-14-20ukushushuluza kwefilimuIzinto ze-PTFE.
2. PTFE ifilimu has a conductivity encane ezishisayo, 0.27W/MK-1 kuphela, kuhambisana lokushisa eliphansi ukumelana nokushisa, izinga lokushisa eliphezulu ukumelana nokushisa 250 ℃ kuphela.Uma ivolumu ye-skiving yefilimu inkulu kakhulu, ijubane lokusika liphezulu, futhi izinga lokushisa lokusika le-workpiece lizokhuphuka, elizothambisa impahla ye-PTFE, ngisho nokuncibilika, ukupheka, kanye "nommese onamathelayo".Ngaphambi kwenqubo yokusika, okungenalutho kwelashwa ngesimo senqubo esingu-30-50 degrees Celsius ngaphezu kwezinga lokushisa elisebenzayo kanye nesikhathi sokuphulukisa esingama-24h noma ngaphezulu, ukuzinzisa ukunemba kobukhulu benqubo yefilimu yokushushuluza.
3. I-Teflon ine-coefficient enkulu yokwandisa okushisayo.Ngakho-ke, impahla ye-PTFE enqubweni yokushushuluza kwefilimu izokhiqiza inani elikhulu lokushisa ngenxa yokungqubuzana, ithuluzi elisebenziseka kalula, kanye nokushisisa okweqile kwendawo.Lokhu kuholela ekuwohlokeni okunwebekayo kocezu lokusebenzela lwe-PTFE ngenxa yokushisa, okugcina kuthinta ikhwalithi ephezulu kanye nokunemba kobubanzi be-workpiece ye-PTFE.
4. Uma kuqhathaniswa nezinto zensimbi, i-modulus yokunwebeka kwe-PTFE iphansi kakhulu.Uma okuphakelayo okusika kukukhulu kakhulu noma isivinini sishesha kakhulu, ukungqubuzana okukhulu kokucubungula namandla asetshenziswa ithuluzi kusebenza ndawonye.Umphumela uba ukuwohloka okukhulu kwe-workpiece ye-PTFE, ethinta ukunemba komshini we-workpiece ye-PTFE.
5 Ukuze uketshezi lokusika ifilimu lusebenze kahle, lezi zimo eziyisisekelo ezilandelayo kufanele zibhekwe: ukusetshenziswa kwamanzi athambile, ukuhlola njalo ukugxilisa ingqondo, ukungezwa njalo kwama-biocides, ukuhlanzwa kwamathuluzi omshini, ukususwa kodaka nesikali, ukuxubana koketshezi lokusika kuqala.
